Frequently Asked Questions
Which cartridge does the M4345XS use?
The Q5945A — the 45A black cartridge shared by the entire family. This listing is a single unit priced at $56.53 with a 20,000-page rating; the stapling hardware that marks out the XS is a finishing feature, not a supply variant.
Why swap early on a stapling machine?
Because the LaserJet M4345XS binds sets as it goes. A cartridge fading through a production run leaves early sets dark and late sets pale — all stapled. Changing at the low warning instead of at visible fade keeps a whole run at one density.
How many pages does a "small" stapled job really use?
More than intuition says. A 30-page document in 40 stapled copies is 1,200 imaged pages — six percent of this cartridge in a single job. Checking the gauge before queueing it is a ten-second habit that saves reprints.
Do copies made for stapling cost extra toner?
No. A copied page costs exactly what a printed page costs; the stapler adds no imaging. What raises consumption is simply the number of pages, whichever door they entered by.
Can the same spare cover an XS and a base model down the hall?
Yes. The family shares one cartridge code from base to fully optioned, so a single shelf spare genuinely covers both machines — one of the quieter economies of running this fleet.
What protection does the purchase carry?
A 1-year warranty and 1-year free returns, set out on our shipping & returns page. Stock ships from warehouses in IL, PA, GA, and CA, with support Monday–Friday, 9 AM–5 PM CST.
About This LaserJet M4345XS Cartridge
The XS pairs the department engine with a stapler, and its documents tend to leave the building. This listing is the supply behind them: the standard 45A black cartridge in our HP compatible range, one unit at a time.
For finishing work, the cartridge's job is consistency more than longevity — full, even density from the first set to the last. Ordering on the warning and swapping on schedule is how that consistency is kept.
